[Message part 1 (text/plain, inline)]

Hi,

I'm not sure if this is a bug or a wrong partition table or something else.
Please read and can you give me advise what to do next?

I'm resizing and moving partitions.
First when starting gparted (systemrescuecd 5.3.2) I got

Assertion (metadata_length > 0) [....] in function add_logical_part_metadata() failed.

and gparted doesn't start

Upgraded to systemrescuecd 6.0.2
gparted (0.33.0) starts but I can't resize the last partition.

parted (version 3.2, option p) displays

Error: Can't have the end before the start! (start sector=83890176 length=0)

fdisk -lu is ok as far as I can see. Starts and ends of partitions are ascending. All data accesible.

Kind regards,
Arno

extended partitions are supposed to have at least 1 sector for metadata.
Some partitioning tools don't enforce this, and parted does so you get
an assertion until you recreate the partition layout.
